METHOD OF PREVENTINGY SHOES FROM SQUEAKING.

SPECIFICATION forming part of Letters Patent No. 471,355, dated March22, 1892.

Application filed October 20, 1891. Serial No. 409,249. (No model.)

To all whom t may concern:

Be it known that I, JOHN C. GALLAGIIER,

of Elmira. in the county of Chemung, in the State of New York, haveinvented new and useful Improvements in Methods of Preventing theSqueaking of Boots or Shoes, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

The Object of this invention is tO provide a method of preventing thesqueaking Of boots Or shoes without soiling or smearing either thebottom Or upper thereof or impairing their shape and finish; and to thatend it consists in the novel method of lubricating the boot or shoe, ashereinafter fully described, and specifically set forth in the claim.

TO render my invention more easily comprehensible, I annex heretodrawings illustrating the method of introducing the lubricant betweenthe layers of the sole of a boot or shoe.

Figure l is a transverse section of the foot of a boot or shoe,illustrating the first step of preparing a passage for the lubricantbetween the two layers Of the sole. Fig. 2 shows the method Of forcingthe lubricant between the layers of the sole, and Fig. 3 illustrates oneInode of causing the lubricant to spread after it is introduced asaforesaid.

In carrying out myinvention I proceed as follows, to wit: I firstinsertan awl a or analogous implement a short distance into the edge of thesole between the layers thereof, as represented in Fig. l of thedrawings, at the same time taking care not to pass the awl through thethread by which the sole is sewed, and thus avoid breaking or injuringsaid thread. After withdrawing the awl I insert into the channel thusprepared the point or needle of a hypodermic or other suitable syringes, as shown in Fig. 2 Of the drawings, said syringe being charged withsuitable lubricant, and by applying pressure On the end of the piston Ofsaid syringe I force the lubricant into the sole, between the layersthereof. In this manner the lubricant is introduced under pressuresufficient to force it the necessary distance into the sole, and thismay be done at any point around the edges of the sole wherever it isdeemed necessary. When this is accomplished and the syringe removed, Iintroduce a last into the boot or shoe and pound the sole, asrepresented in Fig. 3 Of the drawings, and thereby not only close thechannels left by the awl and syringe, but also spread the lubricantbetween the layers of the sole, and this effectually prevents thesqueaking Of the boot or shoe and at the same time renders the soleimpervious to water. All this I effect withoutsoiling` or smearing theupper, as well as the bottom of the boot or shoe, orin any wiseimpairing its shape and finish.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

The method Of preventing the squeaking of boots and shoes, consisting inpiercing the sole from the edges and between the layers thereof, thenforcing the lubricant into the channels formed by said piercing, andthen closing the said channels and spreading the lubricant in 'the soleby subjecting the same to concussions upon the bottom thereof, as setforth.

In testimony whereof I have hereunto signed my naine this 15th day OfOctober,

Isf-n.
